Definitions
- the present invention describes a device for prostate palpation as a screening method for prostate cancer.
- the object of the invention is to provide a device that allows palpation of the rectal aspect of the prostate, identifying areas of high rigidity and the limits of the gland, with the aim of detecting prostate cancer.
- the device is configured to measure force and deformation at points on the rectal side of the prostate, rectally.
- the invention describes a device and a method for palpating the rectal aspect of the prostate, providing an objective and reproducible index for evaluating tissue stiffness.
- the methods and devices described in this invention allow these drawbacks to be overcome, allowing the identification of areas of high rigidity in a completely objective manner, less aggressive, reaching the entire peripheral area, and a test time similar to that of digital rectal examination.
- the device of the invention additionally has an ultrasonic imaging system that allows visualizing the anatomy of the prostate during the test.
- the invention falls within the sector of manufacturers of medical diagnostic devices, as well as the industry dedicated to the treatment of prostate cancer.
- the prostate is a gland that is located below the bladder in men and produces the fluid for semen. Cancer screening tests are done before you have any symptoms, because cancer found early is easier to treat.
- prostate-specific antigen PSA
- the doctor inserts a gloved and lubricated finger into the rectum to feel the prostate and, based on the stiffness of the palpated area, determine a suspected diagnosis.
- the first and biggest problem is the lack of objectivity in the analysis of the stiffness of the palpated area, since it is based on the subjective perception of the doctor regarding the pressure that can be exerted with his finger, which can lead to diagnoses unreliable.
- the force/pressure sensor is large enough to detect pressure or stiffness of the prostate and/or prostate tumors.
- the forces imposed on the sensing device by tumors will typically be greater than those applied by the adjacent rectal wall tissues supported by the benign prostate.
- the force/pressure sensors are rigidly mounted on the probe to ensure that the force measured by the force sensor corresponds to the applied force.
- a pressure/force sensor Due to the physiognomy of the prostate tissues, the punctual application of a pressure/force sensor can give erroneous readings, as it can coincide with small folds so that obtaining different measurements relative to each other is decisive when making a good diagnosis.
- these devices do not include means that allow visualizing the anatomy of the prostate, so that it is not possible to know precisely the specific area that is being explored and even more so, if what is being explored is the prostate.
- the device for palpation of the prostate that is recommended fully solves the aforementioned problems, allowing palpation of the rectal side of the prostate, identifying areas of high rigidity in the peripheral zone of the gland, with the aim of detecting indurations suggestive of prostate cancer.
- the device of the invention is embodied in a manual electronic instrument, provided with a handle for its handling attached to a transrectal exploration rod.
- the control electronics is integrated into the handle, through the corresponding button, as well as a series of indicators that show the results of the measurements obtained.
- the exploration rod has two concentric indenters near its distal end that have different heights, specifically the central one being higher than the external or perimeter one, through which pressure is applied to the exploration point, and that are linked to respective internal pressure sensors through a lever (outer indenter) and a cylinder (inner indenter).
- the device incorporates an ultrasonic imaging system that allows locating and visualizing the anatomy of the prostate, as well as the correct positioning of the pressure sensors.
- the ultrasonic imaging system is based on the use of a "phased array” or phase arrangement, of at least 8 emitting/receiving piezoelectric elements and a central frequency greater than 2 MHz, with at least 50% bandwidth, with cross-sectional focus in such a way that a sectoral section of the prostate can be observed.
- the arrangement of the emitting elements of the transrectal ultrasound imaging system preferably curved to adapt to the cylindrical shape of the stem and come into contact with the tissue, as well as the size and number of these and the separation distance between them, is optimized for not interfere with the correct arrangement of the line of pressure sensors, obtain the best image resolution and the largest aperture and depth of field.
- the transrectal ultrasound imaging system has electronics associated with a wireless communications module or a cable communications interface that allows it to be used with a computer, a Tablet, a Smartphone or another computer device that allows the display of information. ultrasound.
- a transrectal ultrasound imaging system provides a visual reference of the prostate to medical personnel performing the exam in real time.
- the simultaneous performance of transrectal ultrasound allows us to rule out false positives that can cause frequent prosthetic calcifications, which would otherwise be associated with areas of high stiffness.
- the ultrasonic imaging system can be composed of a two-dimensional arrangement of the emitting elements to carry out an electronic addressing of the anatomical image or a one-dimensional arrangement that allows its mechanical rotation from the handle to carry out a low-cost mechanical addressing of the image. anatomical sectoral image.
- the stiffness sensor and the probe may not be aligned with the transrectal ultrasound image, in order to obtain images of different slices of the prostate from the same position of the stiffness sensor and improve exploration and rule out false positives. .
- the ultrasound imaging system may be positioned within the stem such that the ultrasound image includes the area of the pressure sensor and the tissue in contact with it.
- the interior of the stem will include a medium with an elasticity and density that allows the correct propagation of ultrasound using an acoustic impedance matching layer. This arrangement provides additional information about the quality of the contact between the pressure sensor and the tissue, which is used to ensure correct physical contact between the sensor and the tissue.
- this configuration allows echogenic information to be correlated with information from the pressure sensors.
- the device will be inserted through the anus of the patient to be explored through its exploration rod so that through this a mapping of the rectal face of the prostate will be made in order to detect indurated areas that suggest cancer. of prostate.
- the number of sensors could be increased, in order to simplify the use of the device by simultaneously palpating a larger surface.
- a system for palpation of the rectal side of the prostate is achieved that transforms the information collected with the device into objective, reproducible and useful, allowing the identification of areas of high rigidity reaching the entire peripheral zone when, currently, in On many occasions, the finger barely reaches the prostatic apex during the manual procedure, transforming into an objective diagnostic maneuver for prostate cancer that until now has been subjective and unreliable. All this in a short space of time, performed in a less aggressive and more objective way than digital rectal examination.
- the healthcare operator performing the examination must avoid contact between the wall of the intestine and the indenters during the phases of insertion and removal of the device in the rectum.
- the device can incorporate two alternative systems to facilitate maneuvering:
- a retraction system internal to the stem, that retracts the indenters in the body of the stem during the introduction phase and that allows it to be extracted when the area to be evaluated has been reached, by means of a control system in the handle.
- Figure 1 shows a perspective view of a device for prostate palpation made according to the object of the present invention.
- Figure 2 shows an enlarged detail of the control interface located on the handle of the device.
- Figure 3 shows the position of the pressure sensors, located in the mechanical assembly formed by the support base and the articulated lever at the end of the base (raised in the figure).
- the left sensor (10 in the figure) directly receives the force from the inner indenter;
- the inner sensor (11 in the figure) receives the force of the outer indenter indirectly, through the central support of the lever where this second indenter is located.
- Figure 4 shows the set of indenters and base with sensors, assembled in their working position, which is inserted into the exploration stem (3) at its distal end and is closed by a rounded cap (4). It has a support base for the sensors (12).
- the external indenter (5) is integrated into a lever (13), articulated at its end at the base, and transmits the force to the corresponding sensor (11), by means of a central support (14).
- the interior indenter (6) passes through the interior of the exterior (5), being of greater total height, and transmits the force to the corresponding sensor (10).
- the device for prostate palpation that is recommended is constituted from a manual electronic instrument, equipped with a handle (1) for handling, and an exploration stem (3) .
- control electronics is integrated into the handle, with a cover (2) for access to it, so that a button (7) is established on it for managing the device (on or off). ; activation or deletion of readings), as well as a scale (8) in which the different pressure levels (9) are displayed, and may include light indicators (10) to show the measurement results, the equipment's power-up or the state of charge of the the battery, all as can be seen in figure 2.
- two concentric indenters (5-6) are established that have different heights, specifically the central one being higher than the external or perimeter one. to this, the latter presenting a diameter of the order of 5 millimeters, elements through which pressure is applied to the scanning point, and which are linked to respective internal pressure/force sensors through a lever (external indenter) and a cylinder (inner indenter).
- the device includes an ultrasonic imaging system, based on the use of a "phased array” or phase emitters, that is, a set of emitters in which the relative phases of the signals with which each emitter is fed are intentionally varied in order to alter the radiation pattern of the set, in which at least 8 participate.
- a phased array or phase emitters
- elements with a central frequency of at least 2 MHz which allows visualizing a sectorial section of the prostate
- electronics associated with a wireless communications module or cable connection that allows it to be used with a computer, a Tablet, a Smartphone or another computer device that allows the visualization of the ultrasound information.
- the device allows simultaneously transmitting the force exerted by two indenters (5 and 6) to two sensors (10 and 11), by means of a lever mechanism (13) with central support (11) and external indenter ( 5), and with a concentric internal cylindrical indenter (6).
- the healthcare operator performing the examination must avoid contact between the wall of the intestine and the indenters during the phases of introduction and removal of the device in the rectum.
- the device can incorporate two alternative systems to facilitate maneuvering:
